BENJAMIN H. ERWIN, OF MISHAWAKA, INDIANA, ASSIGNOR TO THE INDESTBU C TOTRUNK COMPANY, OF MISHAWAKA, INDIANA, A CORPORATION OF OHIO TRUNK LOCKAND GOVEEED BAIL Application fi1ed May 7,

My invention relates to improvements in trunk locks and covered bail,and it more especially consists of the features pointed out in theannexed claims.

The purpose of my invention is to provide a combine-d opening andclosing bail and lock; that'completely covers the bail when the trunk islooked; that is free from external projections; that afiords amplelength ofleverage of the covering member to which the bail is pivotedand which carries the lock near its free end; and that provides flangedbase plates on the adjacent portions of a trunk body and its cover withwhich the bail, the covering member, and the attaching member areassociated.

With these and other ends in view, I illustrate in the accompanyingdrawings such instances of' adaptation as will disclose the broadunderlying features of the invention without limiting myself to thespecific details shown thereon and described herein.

side ;while disconnected from each other.

The device is applied to all types of receptacles, such as trunks, etc,in which two, parts are to be held'assembled and locked, whilepermitting the parts to beforcibly pushed apart when unlocked and asforcefully pulled togetherpreparatory to locking them against movement.In addition to these cooperating features the device completelycoversthe actuating bail, which in devices of this general type have not beenenclosed heretofore.

As exemplified in the drawings the body of the receptacle is designatedby the numeral 1, and the'oover,door or lid by thenumeral 2. A baseplate 3'is secured to the body. It has abeveled flange 20 along its topand hottomand the rounded end, shown inlFigsl 1, 2 and 3. A companionbase plate 4-is attached to the part 2. Both plates are positioned inalignment with each. other asshown in Fig. 2. The extreme end 30 formsan abuttin'g edge against which the swinging bail ll pushes when thetrunk or receptacle, is to be opened by pulling'the free end ofthecoveringmember 6 outward. This alternative construction is shown inFig.4 and a simplified modificationisshown in Figs.,8 and 9.

Amember 5having a rim flange 23 and a raised boss 27 is, seated inthebase plate 4 with its boss positioned in-the recess 260f the boss 25. QAbolt ;24 passes throughthe parts 4 and 5, andthe adjacent wall of thereceptacle serves to holdtheparts in rigid engagement witheach other.This part5 has tworecesses 35 formedat its edges, as shown in Figs. 1, 3and 5, intowhich the forked ends 34 of the covering memberG arepositioned.

' These ends 34 are pivoted on the longpin 12 reaching from top tobottom of theffpart 6 andthe part 5. In this way the covering member 6is supported by the part5. The

projections 34 have" pivoted thereon .the

forked ends 32 of the bails 11 or 36 by means of short pins 13, as shownin Figs. 4, 5, .8 and 9.- The swinging covering member 6 carries thelock 7 whose bolts 8 pass behind the base plate 3 whenever therequiredkey is used to actuate the bolts. The casing ofthelock- 7 passesthrough, the openingl'l into afrecess pin 12. The bail has an opening 29inside" of a loop 19 designed to permit the lock 7 to freely passtherethrough. This action of the bail causes the'loop 19 to abut theinner edge 9 of the beveled flange 30 (shown in Fig. 3) during the firstpart of the movement of the member 6. As the free end of this member ispulled out further from the base plate 3, the parts 1 and 2 areforciblypushed apart, as shown in Fig. 3, at 33, when the'bail 11 may be swungoutward away from the curved stop 10 and the parts 1 and 2 opened-marginal beveled flange 21, similar to the :treefends resting on thelong to whatever extent is desired.

To close the trunk the parts 1 and 2 are brought fairly close together,so that the loop 19" will pass over the curved stop 10, when the covermember 6 is pushed inward. This causes the loop 19 to engage the curvedstop 10 as shown in Fig.1 during the first part of the movement of themember 6. movement of this member (see Fig. 4) causes the'bail 11tojpull the parts tightly together. When the member 6 is pushed all theway in it isheld inplace by the lock 7.

To assist in first moving themember 6 outward after the bolts 8 havebeen drawn,

springs 14, shown in perspective in Fig. 6, are mounted on the shortpins '13 with their pin 12. Provision is alsomade for easily pulling theloop 19 and the bail 11 away from the curved stop 10 through a shorttongue 18 which projects inwardly from the loop across the recess 31,

as shown in Figs. 1 and 3. I The base plate 4: is also provided with aflange 20 ofthebase plate 3, andthe member'6 has a marginal flange 22.These flanges cooperate to entirely enclose the inner mecha- -nis'msothat thefront edges of the flanges20 and21are almost flush with thefront face of the members 6 and 5, and by reason of the flanges 22 and23 passing inside of the flanges 20 and 21 and the closed end 30 thereis no opportunity to insert a screw driver beneath f the members 5 and 6to forcibly break into the trunk. As the bolts 8 are beveled the lock 7is selfacting whenever the member 6 is moved its full distance towardthe base plate The base plates 3 and tare riveted to the walls of'thetrunk and, as stated, the bolt 24 serves tohold the locking, theopening, and

closing meansassembled as a unit;

'plates3'an'd 4. Theplate 3 has a recess It comprises. the. base formedto receivethe lock 7 and it'also has a projection 39. overwhichthesquared hole 38 V of the. shortened bail 36'passes. A- bent i Furthertongue 37 serves to make it easy to grasp hold of it when the bail is tobe pulled away from the projection 39. Y The operation'of the parts issubstantially the same whether the long bail 11 or the short bail 36 isused or whether the projections 10 and 30' are used (Fig. 4) or theprojection 39 is used inbase plates 3 and 4 may be transposed from thebody to the door and vice versa. What I claim is: I 1. In trunks, a pairofbase plates in alignment with each other, a flange bordering-thelextreme outside of both plates except at their adjacent edges, alocking member having an inner flange positioned inside and adjacent tothe flange of the one base plate, a supporting plate having an innerflange positioned inside and adjacentthe flangeof thesecond base plate,means for pivoting the locking member onto the supporting plate, aswinging bail pivoted to the locking member and positioned between thelocking member and the first base plate, and cooperating means betweenthe bail and said base plate adapted to hold the'bail and the plate infixed rela tion to each other as the locking member is moved on itspivot to move the base plates toward or from each other.

2. In trunks, a pair of base plates secured respectively to a stationaryand a movable part of a trunk and in alignment with each other, a flangealong the extreme outeredge of both plates except at theiradjacentedges, a two part locking member having its edges terminate adjacent toand within the flanges of the base plates to enclose the underside ofthe locking member when said member engages both plates, a pivot betweenthe'two parts of the locking member joining a stationary and a swingingpart, means for attaching the stationarypart to the base plate of oneportion of the trunk, a bail pivoted on the inside of the swinging part,a projection on the other base plate, cooperating means between the bailand the projection adapted to hold the bail and said projection inengagement with each other as the swinging part of the locking member isswung on its pivot to move-the base plates toward or from each other,anda key lock on the locking member adapted V to engage the cooperatingbase plate. I In testimony whereof'I afiix my signature.
